Vedclass · Answer

(A) Characteristic $X$-rays are produced due to the transition of electrons from higher energy levels to lower energy levels within the atoms of the target material.Since the energy levels in an atom are quantized,the energy difference between these levels is fixed for a specific element.Therefore,the emitted $X$-ray photons have specific,discrete energies and corresponding wavelengths.These wavelengths depend solely on the atomic number of the target material and are independent of the kinetic energy of the incident (projectile) electrons,provided the energy is sufficient to knock out an inner-shell electron.
